ATTACHMENT FOR Dl IRT MOVING MACHINES Filed June 4, 1931 5 Sheets-Sheet s r c q VT- Invenlor Q ficuyfi Patented May 17, 1932 CHARLES J. HAUGH, F ALTJIA, NEBRASKA ATTACHMENT FOR nm'r MOVING MACHINES Application filed June 4., 1931.

The present invention relates to an attachment for a dirt moving machine and has for its prime object to provide means to keep the dirt from accumulating between the runs of a conveyor on a dirt moving machine.

Another very important object of the invention resides in the provision of an ap paratus of this nature which may be readily installed on a dirt moving machine and is simple in its construction, inexpensive to manufacture and install, thoroughly efficient and reliable in use and operation and other- Wise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a fragmentary view of a dirt moving machine showing my apparatus incorporated therein.

Figure 2 is a perspective View of the rocker and associated parts.

Figure 3 is a detail elevation of the upper sprocket showing the crank and pitman.

Figure 4 is a top plan View of the plate, and

Figure 5 is a side elevation thereof.

Referring to the drawings in detail it will 7 be seen that the numeral 5 denotes a steel plate mounted between the upper and lower runs of a conveyor 6 near the lower end thereof and next to the lower rollers. On this plate is a pair of scraper arms 7 mounted on edge and just large enough to pass between the plate and the upper run of the conveyor. These scrapers are guided to run true on the plate by having openings through which extends a rod 8 having one end turned down and anchored in one end of the plate as at 9 while the other end is anchored in an angle iron bracket 10 on the other end of the plate. These scrapers are connected together in spaced parallel relationship by rods 11 and one of the plates has an eye bolt 12 in an in- Serial No. 542,162.

termediate portion thereof with which is engaged an eye 14 on a rod 15.

A. sprocket 17 is mounted on one of the wheels 18 of the dirt moving machine while a sprocket 19 is mounted on a shaft 20 journalled in a bearing 21 at the top of the machine. This shaft is formed in the present instance with a crank 22 with which is engaged a pitman 23. A chain 24: is trained over the sprockets 17 and 19. Numeral 25 denotes a rocker an intermediate portion of which is pivoted on a bracket 26. The upper end of the rocker is engaged with the pitman 23 while the lower end thereof is engaged with rod 15. It will therefore be apparent that as the machine moves along and the wheel 18 turns said rocker will be caused to oscillate thereby causing reciprocation of the scrapers longitudinally on the plate 5 thus preventing accumulation of dirt between the aprons.

It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combina tion and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

In an apparatus of the class described, an elongated plate, a rod mounted longitudinally along the plate, a pair of scrapers having openings to receive the rod and slidable on the rod and the plate, means independently of said rod holding the scrapers in spaced relation to each other, means for reciprocating the scrapers back and forth on the plate longitudinally thereof, said means comprisinga rocker, a rod connecting one end of the rocker With one of the scrapers, a shaft having a crank, a pitman connected With said crank and said pitman being connected With said rocker, a sprocket on said shaft, a second sprocket adapted to be connected With the Wheel of a dirt moving machine, and a chain trained over said sprockets for transmitting movement of said Wheels to said shaft.

In testimony whereof I afiix my signature.

CHARLES J HAUGH.
